Detailed Description

In order to make the technical problems, technical solutions and advantageous technical effects to be solved by the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the present application. It is noted that directional terms used in the description refer to the normal use state of the cleaning device for convenience of description and are not to be construed as absolute limitations of the corresponding features.

Fig. 1 shows a perspective view of a cleaning device 1 according to one embodiment of the present application.

As shown in fig. 1, the cleaning device 1 is exemplarily configured as a handheld cleaning device 1 and comprises a housing 10. The housing 10 is injection molded from a plastic material and is partially constructed as a volute. Alternatively, it is also possible to press-form the housing 10 from a lightweight sheet metal in order to increase the overall strength and texture of the housing 10. In the present application, the cleaning device 1 is not limited to a specific appliance, but may be designed, for example, as a hair remover, a hand-held cleaner or the like. A handle 50 is constructed on the housing 10, which handle 50 can be grasped by a user to operate the cleaning device 1.

An air inlet 101 and an air outlet 102 are formed in a volute portion 104 of the housing 10. Air flows in the volute section 104 via the air inlet 101 towards the air outlet 102. In the view of fig. 1, the air inlet 101 is configured on the bottom side of the volute section 104. The air outlet 102 is formed on a side of the volute portion 104 perpendicularly with respect to the air inlet 101. Thus, the air flow is deflected 90 degrees in the volute section 104.

The air outlet 102 is configured as a mesh type air outlet 102, which mesh type air outlet 102 is adapted to allow only air to be guided out of the air outlet 102 without allowing dirt to flow through. The size of the mesh openings can be tailored to different soil sizes. For example, for a hair remover, the mesh size may be designed to be at least smaller than the diameter of the hair. Whereas for a hand-held cleaner the mesh may be designed to be smaller than the size of the dust, even an air-porous sponge or the like may be additionally arranged at the air outlet 102 to prevent the dust from flowing out of the air outlet 102.

The cleaning device 1 further comprises only one roller brush arrangement 20, only one drive arrangement 30 (not shown in this view, see also fig. 3) and an energy supply arrangement not shown in detail. The roller brush device 20 includes a roller 201, a rotation shaft 204 of which is supported in the housing 10. The drive 30 is configured as an electric motor and the energy supply is configured as a battery (not shown). The battery powers the motor to cause the motor to drive the roller brush arrangement 20 in rotation. In this embodiment, the roller brush device 20, the drive device 30 and the energy supply device are all arranged in the housing 10. The rolling brush device 20 is made of an antistatic material and prevents dirt from being adsorbed on the rolling brush device 20 due to static electricity.

Furthermore, the cleaning apparatus 1 further includes a dust box 40, and the dust box 40 is detachably disposed on the housing 10 and is capable of collecting the sucked dirt. The dust box 40 is provided with a dust collecting opening (not shown in detail) for receiving dirt. A first opening 1031 communicating with the dust collection opening of the dust collection box 40 is opened on the inner wall of the outlet passage 103 of the housing 10. Dirt, such as hair or dust, is caught at the air outlet 102 and can fall from the outlet channel 103 into the dust box 40 due to gravity.

Fig. 2 shows a top view of the cleaning device 1 in fig. 1. The air inlet 101 is configured as a rectangular opening and extends lengthwise in the width direction of the housing 10. The handle 50 is disposed substantially centrally with respect to the housing 10 at one end of the housing 10.

Fig. 3 corresponds to fig. 2 and shows a top view of the main structural parts of the cleaning device 1 in fig. 1.

As shown in fig. 3, the driving shaft 301 of the driving device 30 is arranged in parallel with the rotation shaft 204 of the roller 201, and the driving device 30 drives the rotation shaft 204 through a transmission device, not shown, such as a belt transmission device or a gear transmission device, or the like.

A roller brush 202 and a wind blade 203 extending longitudinally in the axial direction (in the direction of the rotation shaft 204) are formed on the outer periphery of the roller 201.

Next, a specific structure of the roll brush device 20 is further described with reference to fig. 4 and 5.

Fig. 4 shows a perspective view of the roller brush arrangement 20 of the cleaning device 1 in fig. 1. As can further be seen from fig. 4, the fan blades 203 are configured longitudinally and consecutively in the axial direction. The roller brush portion 202 is configured as, for example, a colloidal bristle. The fan blade 203 and the roller brush 202 are spaced apart and uniformly distributed in the circumferential direction of the roller 201. In this embodiment, the blade 203 is integrally formed with the roller 201, and the brush 202 is detachably disposed on the roller 201.

Fig. 5 shows a side view of the roller brush arrangement 20 of fig. 4. According to this embodiment, five identical roller brush sections 202 and fifteen identical fan blade sections 203 are formed on the periphery of the roller 201, wherein three evenly distributed fan blade sections 203 are respectively provided between every two roller brush sections 202. As shown in fig. 5, the blade 203 is configured to be shorter than the roller brush 202, and the blade 203 and the roller brush 202 are configured or arranged obliquely in the rotation direction R of the roller 201.

Fig. 6 shows a side view of the cleaning device 1 in fig. 1.

The roller brush 202 can protrude from the plane of the air inlet 101 of the housing 10 and come into contact with the surface to be cleaned during rotation of the roller 201, so as to carry dirt on the surface to be cleaned up and accumulate in the direction of the air inlet 101. The blade 203 is always located within the housing 10 and is not in contact with other structures during rotation of the roller 201. The blade part 203 generates an air flow by a rotational movement and creates a negative pressure at the air inlet 101 to generate a suction force so as to suck dirt from the air inlet 101 into the housing 10, and the dirt is guided in the rotational direction R with the air flow toward the air outlet 102.

As fig. 6 shows again, since the air inlet 101 is perpendicular to the air outlet 102, dirt is sucked in radially from the air inlet 101 (relative to the roller 201) and moves in the volute section 104 in the tangential direction of the roller brush arrangement 20 or the roller 201 in the air flow direction L towards the air outlet 102 and is deflected by 90 degrees in the volute section 104.

According to this embodiment, the configuration of the roller brush arrangement 20 and the volute section 104 employs the principle of a cross-flow fan. That is, the inner wall of the housing 10 of the volute section 104 has a shape substantially approximating an archimedean spiral. Since the blade 203 has the same size, the outer edge of the blade 203 forms the reference base circle 2021 when the roller 201 rotates. From the air inlet 101 to the air outlet 102 in the direction of rotation R, the radial distance of the outer edge of the fan blade 203 or the reference base circle 2021 from the inner wall of the volute becomes gradually larger.

As can be seen from fig. 6, the first distance a between the fan blade 203 in the vicinity of the air inlet 101 and the inner wall of the housing 10 is smaller than the second distance B between the fan blade 203 in the direction of the air outlet 102 and the inner wall of the housing 10. Thus, a diffuser-like structure is formed in the housing section defined from the air inlet 101 to the air outlet 102 along the direction of rotation R and enables the air flow to flow out mostly toward the air outlet 102 and the air flow to be stabilized.

As the air flow continues to be directed in a horizontal direction (in the view of fig. 6) in the outlet channel 103 and out of the air outlet 102, dirt is blocked by the mesh air outlet 102 and falls into the dust box 40 (see also fig. 1). Dirt on the surface to be cleaned can thus be sucked and collected in the dust box 40 conveniently and easily by the present application.

Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the disclosure even if only a single embodiment is described with respect to a particular feature. The characteristic examples provided in this disclosure are intended to be illustrative, not limiting, unless stated otherwise. In a specific implementation, the features may be combined with one another where technically feasible according to the actual requirements. Various substitutions, alterations, and modifications can be made without departing from the spirit and scope of the application.
